编译 Systemd 独立二进制文件时遇到问题

  • 772

来源：systemd-stable-251：https ://github.com/systemd/systemd-stable

wget https://github.com/systemd/systemd-stable/archive/refs/heads/v251-stable.zip
unzip v251-stable.zip 
cd systemd-stable-251-stable/

使用命令：

./configure --auto-features=disabled \
            --default-library=static \
            -D standalone-binaries=true \
            -D static-libsystemd=true \
            -D static-libudev=true \
            -D link-udev-shared=false \
            -D link-systemctl-shared=false \
            -D link-networkd-shared=false \
            -D link-timesyncd-shared=false \
            -D link-boot-shared=false && make

还尝试仅使用静态库并仅启用独立选项。

配置：

用户定义选项 auto_features : 禁用 default_library : 静态 link-boot-shared : false link-networkd-shared : false link-systemctl-shared : false link-timesyncd-shared : false link-udev-shared : false 独立二进制文件 : true static -libsystemd：真静态libdev：真

共享对象：

# file build/udevadm
build/udevadm: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=f6b7c1a3509d45ebcafda9b49f4dd2332e786738, with debug_info, not stripped

我期待看到一个 ELF 可执行文件而不是共享对象文件。

    选项的文档standalone-binaries说：

    还构建支持的二进制文件的独立版本

    这似乎充其量是模棱两可的。查看meson_build文件，我们发现：

            if have_standalone_binaries
                exe = executable(
                        'systemd-sysusers.standalone',

[...]

        if have_standalone_binaries
                exe = executable(
                        'systemd-tmpfiles.standalone',

[...]

    这似乎表明该选项仅影响systemd-sysusersand systemd-tmpfiles，实际上，当构建完成时，我们看到：

    $ ls build/*.standalone
build/systemd-sysusers.standalone build/systemd-tmpfiles.standalone

    看起来事情正在按设计运行。
